UNITED STATES ROBERT W. PAIN, OF NEW YORK, N. Y.,

PATENT OFFICE.

ASSIGNOB, BY MESNE ASSIGNMENTS,

TO THE NATIONAL AUTOMATIC PIANO AND ORGAN MANUFACTURING COMPANY, OF NEW YORK.

' SPECIFICATION forming part of Letters Patent No. 270,606, dated January 16, 1853,

Application filed March '23, 1882. (No model.)

To all whom at may concern Be it known that I, ROBERT WV. PAIN, of the city, county, and State of New York, have invented a new and useful Improvement in De- 5 vices for Operating Take-Up Rolls of Mechanical Musical Instruments, of which the following is aspecification.

In certain mechanical musical instruments that are operated or controlled by perforated I music sheets the crank-shaft of the take-up roll is connected with the wind-pumps or bellows in such a manner that both are moved at the same speed when the instrument is in operation, which construction is faulty, for the reason that though quick motion is desirable and even necessary for the effective action of the pumps a low rate of speed is more desirable for the roll.

The object of this invention is to overcome this objection by imparting high speed to the pumps and low speed to the roll by the same movement of the crank-shaft.

The invention consists in the peculiar construction, operation, and combination of parts,

2 as morefully hereinafterdescribed and claimed. Figure 1 is a side elevation, showing my improved device applied to a take-up roll. Fig. 2 is an enlarged plan of the same. Fig. 3 is a front elevation of the same.

Similar letters of reference indicate corresponding parts.

In the drawings, A represents a frame, on one end of which are secured standards A, supportingtherewinding-roll B, on whose shaft or axle is fixed a crank-handle, l3, f'orrevolving the same.

O O represent the standards supporting the take-up roll I), which is provided with a deep flange, I), at either end.-

E represents a rocking frame, consisting of standards E, pivoted at a, on opposite sides of the'frame A, and connected by a cross-bar, E Journaled in said standards Eis acrank' shaft, F, on which is fixed, near each end, a friction-roll, F, opposite each take-up-roll flange D, while springs G, secured at their lower ends on blocks G, that are fastened to the sides of the frame A, bear with their upper ends against theupper ends of the standards E, and thereby force the friction-rolls F in contact with the flanges D.

A lug, I), projecting from one of the standards O, serves as a fulcrum for an eccentric cam, H, which maybe moved by a handle, H, against a standard, E, to. force the rocking frameE, and thereby the rolls F, rearward, the latter from contact with the flanges D.

Connecting rods or'pitmen K, engaged on the cranks or wrist-pins d of the shaft F, are designed to be connected with the air-pumps or bellows (not shown) of the instrument.

L represents the handle of the crank-shaft F, and M the perforated music-sheet. When the latter is suitably affixed to the two rolls B D, and it is desired to roll or wind it upon the talie-up roll D, and at the same time to move the pitmen K to operate the pumps, (not shown,) the operator turns the handle L, thereby giving to said roll D a relatively much lower speed than that of the pitmen K, the flanges D being of much greater diameter thanthe l'riction-rollsF, by contact with which they are made to revolve for thevpurpose of winding up the sheet M. When it is desired to rewind the sheet M the cam-handle H may be moved in the direction of the arrow 00, Fig.

1, with the effect of throwingthe friction-rolls' F out of gear with the flanges D, so that the roll I) may freely revolve toward the roll B when the latter is turned for rewinding the 8c said sheet M.

I do not broadly claim friction-rolls as a means for transmitting mot-ion to a take-up roll of a mechanical musical instrument; nor do I claim the use of friction-rollsin combination with an intermediate roll bearing against the flanges of the take-up roll; and I am aware of the patent of M. J. Matthews, dated February 22, 1582, No. 238,138, and 1 do not claim the construction shown in said patent.

What I claim is The combination, with the shaft of the roll I), mounted in stationary bearings, ot' the crank-shaft F, mounted in, two pivoted standards, E, the spring G on one side of the stand- 5 ards, the cam H on the opposite side, the wheels FD, and the cranks K, all constructed and operating substantially as and for the purpose specified.

ROBERT W. PAIN.
